摘　　要：目的探讨乳杆菌DM8909裂解物在体内外对金黄色葡萄球菌、大肠埃希菌的抑制作用。方法通过对乳杆菌超声波破碎制成裂解物,分别用乳杆菌裂解物原液、裂解物稀释液、发酵上清液、乳杆菌活菌制剂进行体内、体外实验,观察乳杆菌各成分对金黄色葡萄球菌、大肠埃希菌的抑制作用。结果德氏乳酸杆菌裂解物对金黄色葡萄球菌、大肠埃希菌的抑制作用与乳杆菌活菌制剂的抑制作用相近。结论德氏乳酸杆菌裂解物在体内外对金黄色葡萄球菌、大肠埃希菌均有较强的抑制作用。Objective To explore the effects of inhibition of Lactobacilli lysates on E. coli,Staphylococcus. Methotis By ultrasonic,Lactobacillus were broken into lysates. Lactobacillus lysates dope,lysates dilution, fermentation supematant and lactobacillus were used in vivo and in vitro experiments, to observe the inhibition effect of the components of Lactobacillus on Staphylococcus aureus and E. coli. Result The inhibition effect of Lactobacillus lysates was similar to the lactobacillus on Staphylococcus aureus and E. coli. Conclusion Lactobacillus lysates have strong inhibition effect against Staphylococcus aureus and Escherichia coli in vivo and in vitro .
